ABSTRACT
Investigation into reports of pain treatment for abdominal cancer and abdominal pain syndromes revealed the lack of human studies on some of the abdominal sympathetic ganglia. Recent studies on renal artery denervation therapy as treatment for resistant hypertension has made the aorticorenal ganglia of particular importance. The aim of this study was to investigate the location, morphology, interconnections, and histological nature of aorticorenal ganglia. We dissected nine abdominal cavities and harvested 37 aorticorenal ganglia. Hematoxylin and Eosin, and Masson's staining techniques were used to study the histological structure. Additionally, ganglia harvested from five individuals were stained with immunohistochemical techniques to test for tyrosine hydroxylase activity. All aorticorenal ganglia were located in proximity to the renal artery, and the majority were close to the vessel origin. Identification of multiple aorticorenal ganglia was the norm, and ranged from 2 to 4 on the left and 1 to 3 on the right. While the pattern of aorticorenal ganglia seemed to be unique in each individual case, the interconnections between these and other ganglia were vast. The aorticorenal ganglia shared direct connections with the celiac, gonadal, inferior mesenteric, and first lumbar sympathetic trunk ganglion. Contributions from the greater, lesser, and least thoracic splanchnic nerves were also observed. While the results of our study may not have direct clinical implications in isolation, the vast number of interconnections with the other abdominal ganglia may cause complications in procedures such as celiac ganglion block. In addition, aorticorenal innervation interruption may lead to hypotension.
